Ingredients
- 1 sheet puff pastry, thawed but cold
- 12 oz beef tenderloin, cut into small cubes
- 8 oz cremini or button mushrooms, finely chopped
- 1 small shallot, finely chopped
- 2 tablespoons butter
- 1 tablespoon olive oil
- 1 teaspoon fresh thyme leaves
- 1 tablespoon Dijon mustard
- 1 egg, beaten
- Salt and black pepper, to taste
- 1 tablespoon chopped fresh parsley, optional
How to Make Mini Beef Wellington Bites
1. Prepare the Mushroom Filling
Melt the butter in a skillet over medium heat. Add the chopped mushrooms and shallot, then cook for 8–10 minutes until the mushrooms release their moisture and become deeply browned. Stir in the thyme and season with salt and pepper. Let the mixture cool completely.
2. Season the Beef
Pat the beef cubes dry with paper towels. Season them with salt and black pepper. Heat the olive oil in a skillet over high heat and quickly sear the beef on all sides, working in batches if necessary. The beef should be browned outside but not cooked through. Transfer to a plate and let it cool.
3. Prepare the Puff Pastry
Preheat the oven to 400°F (200°C). Line a baking sheet with parchment paper. Roll the cold puff pastry slightly on a lightly floured surface and cut it into approximately 3-inch squares, making enough pieces to wrap the beef.
4. Assemble the Bites
Brush a small amount of Dijon mustard onto each cooled beef cube. Place a spoonful of mushroom filling in the center of each pastry square, add the beef, and fold the pastry around the filling. Pinch the seams closed and place each bite seam-side down on the baking sheet.
5. Add the Egg Wash
Brush the tops and sides of the pastry with beaten egg. Leave a little space between each bite so the pastry can puff and brown evenly.
6. Bake Until Golden
Bake for approximately 15–20 minutes, or until the pastry is puffed and golden. Because these bites contain beef, use a food thermometer to check that the center reaches a safe temperature for the desired doneness. For whole beef cuts, the USDA recommends 145°F (63°C) followed by a 3-minute rest.
7. Serve Warm
Let the bites rest for a few minutes before serving. Garnish with fresh parsley if desired and serve warm with extra Dijon mustard or a creamy horseradish sauce.
Tips for the Best Mini Beef Wellington Bites
- Keep the pastry cold: Cold puff pastry is easier to handle and produces a flakier finish.
- Cook the mushrooms thoroughly: Remove as much moisture as possible to prevent soggy pastry.
- Cool the filling: Hot ingredients can soften the pastry before baking.
- Avoid overfilling: A small amount of mushroom mixture and one beef cube per square helps the pastry seal properly.
- Seal the edges well: Pinch the seams together to keep the filling inside while baking.
- Prepare ahead: Cook the mushroom filling and sear the beef in advance. Assemble shortly before baking for the best texture.
Final Thoughts
Mini Beef Wellington Bites are an elegant addition to any appetizer spread. With savory beef, rich mushroom filling, and crisp golden pastry, these little bites are perfect for holiday gatherings, cocktail parties, and festive dinners.
